<p>For a conceptual overview of event tracing, see the Microsoft Windows SDK. For information about tracing tools, see the Windows Driver Kit (WDK).</p>
<h2>Remarks</h2>
<p>After using this extension, you must resume program execution (for example, by using the <a href="#Bookmark1997"><b>g (Go)</b></a> command) in order for it to take effect.  After a brief time, the target computer automatically breaks into the debugger again. </p>
<p>To disable a provider, use <a href="#Bookmark2815"><b>!wmitrace.disable</b></a>. </p></div></div>
